Printing Nozzle Check Pattern - Brother GTX-4 Service Manual

Printing nozzle check pattern

By printing out a nozzle check pattern, you can check on the printing quality.
It is recommended to always perform this procedure to verify the output.
<TIPS>

The serial number, firmware version, and print date (day/month/year) and time are printed at the bottom of the nozzle check
pattern.
The date and time will be printed in Coordinated Universal Time with "(UTC)" printed at the end if time adjustment as a
maintenance tool has not been made. You can print the date and time according to your environment by making time
adjustment. For details of time adjustment, refer to "2-5-6. Setting of the time displayed on the nozzle check pattern ".
(1) Put the platen 14X16 in place, and position its level at "A".
(2) As illustrated below, put the A4-size or letter-size white paper on the platen in alignment with the right-hand corner
of the platen at its front edge.
When the paper is loosely fitted, fix its edge with a tape or the like.
A T-shirt can also be used instead.
<TIPS>

When printing out a nozzle check pattern on the white side, print it on a pretreated black or dark color textile or black paper,
or a transparent sheet (such as OHP sheet).

(3)
Then, printing will begin.
After printing on the color side is completed, remove the printed paper and replace it with a paper for printing on the
(4)
white side.
(5) From the menu, select [Test Print] > [Nozzle Check White], and press
Then, printing will begin.
(6) Check to see if the printed result of both sides are acceptable, and if no ink-jet droplets have been ejected, perform
a head cleaning for print heads.
<IMPORTANT>

If the print result shows an intermittent line, non-ejection has occurred. A head cleaning should be performed on the print
head that has a poor nozzle check result.

Even when the lines of the print results of white side are too light, it does not affect the quality because the white ink is
ejected at the same position through multiple nozzles.
